For each record summary, when and where possible, we have excerpted
the summary data from the original resource to provide sufficient
information about its subject coverage, and other features, to enable users
to judge a resource's potential usefulness.

No attempt has been made to standardize the form of the
data provided for each record. Only when necessary are other sources consulted for additional information
about the resource. It is hoped that this approach will greatly expedite the
description of the resource and its incorporation within CyberStacks(sm).
